What should you do if you need to establish radio communication after being intercepted?

If you find yourself in a situation where you need to establish radio communication after being intercepted, using the emergency frequency of 121.50 MHz is the appropriate action. This frequency is recognized globally as the emergency frequency for aviation distress and should be used when standard communications have failed or if there is an immediate need to communicate with air traffic control or other aircraft. It is designed for urgent situations, allowing pilots to relay crucial information effectively.

In an interception scenario, being able to communicate your situation and intentions is vital for ensuring safety and compliance with the instructions from the intercepting aircraft. The emergency frequency is monitored by air traffic services and other aircraft, increasing the likelihood of a prompt response.

Other choices may not be suitable for this scenario. Changing to a frequency like 120.00 MHz, often used for common traffic advisory frequency in uncontrolled airspace, would not guarantee that the intercepting aircraft or authorities are listening there. Communicating on a private frequency is inappropriate for an emergency situation as it could hinder communication with those who need to be aware of the situation. Attempting to land immediately without communication may not provide the best outcome, especially if the intercepting aircraft is signaling instructions that need to be followed for safety. Using the emergency frequency ensures that you are
